I thought it went bad at season 9 too, but I looked at the episode list for it and there are actually some episodes that I liked quite a bit. I was surprised this episode was from that late in the show, for instance. Granted there are a few really terrible ones in season 9 as well. Season 10 and beyond are all just crap though.

You should make another one where it loops for a few seconds and the gun discharges into Marge's face and/or vagina. Preferably the vagina. She's already had her children and her birthing years are well behind her. Hopefully you miss the artery, but her death could add a few more sh*tty seasons to the show.
